You have keys for games that have been in bundles. You usually can only trade those for other bundle games. They aren't worth their retail cost anymore. I'd go around .70 in cards (random or complete sets) for retrovirus or offer you a game from my list here
Scourge is about 2key value.
Best of luck trading.

I want Halo: Spartan Assault and Scourge: Outbreak
This is how it'll work:
First, I give you the Steam key for Retrovirus.
Then, you'll give me what I want.
Lastly, I'll give you the Steam key for Guns of Icarus Online.
Worth of what I'm giving: About 30€
Worth of what I want: About 15€
Not that sure how this site works, only now started using it.
